Vladimir Konstantinovich Arkadyev (21.04 1884—1.XII 1953) was a Soviet physicist and a corresponding member of the USSR Academy of Sciences (1927). He was born in Moscow. He graduated from Moscow University (1908), where he worked until 1911, and then at the L. A. Shanyavsky People's University. He began his scientific work in 1907 under P. N. Lebedev. In 1919 he set up a magnetic laboratory at Moscow University, which he headed to the end of his life (now the J. Maxwell Laboratory of Electromagnetism). From 1932 he was professor at the university and from 1939 head of a department. In 1923-31 he was also head of a department at the State Experimental Electrotechnical Institute.
His work was mainly on magnetism. Studying the properties of magnetic substances in the alternating fields of ultrahigh-frequency waves, he detected in 1913 the selective absorption of the energy of an alternating field in ferromagnets, a phenomenon later named ferromagnetic resonance, and worked out a theory of it. He introduced the idea of magnetic viscosity. He proposed a generalised law of electromagnetic induction. His work laid the foundations of magnetic spectroscopy. He also studied Fresnel diffraction.
He founded a school of physicists (B. A. Vvedensky, N. S. Akulov, V. A. Karchagin, N. N., P. S. Kudryavtsev, A. V. Peryshkin and others)
